N. Y., A CORPORATION OF NEW YORK rrnsnrne ARM non sAuiTAnY WATER CLOSET ATTAcnmENT's' Application filed February 19, 1931-. Serial No. 516,858.

This invention relates to plumbing appliances and more particularly refers to improvements in sanitary attachments for water closets and bidets of the type where a nozzle bearing arm is brought from an inoperative to an operative position for direct,- ing a jet of fluid against the body of the occupant of the seat for cleansing purposes.

Sanitary water closet attachments ofthe type to which this invention refers have been described and claimed by us in our copending applications, entitled: Method of and apparatus for sanitary cleansing, Ser. No. a83,23 l; Cleansing nozzle for water closet, Ser. No. 485,440; Sanitary bowl with hydraulic dryer, Ser. No. 487,410; Sanitary water closet attachments, Ser. No. 196,898.

In the application last mentioned especially, we have described an arrangement in which a flushing or water delivery arm is brought by the cam action exerted by a plunger member from an inoperative position under the rim of the watercloset bowl to an operative position where the nozzle provided at the end of said arm comesto occupy a position within the bowl in which its axis remains on a vertical longitudinal plane passing through the center of the bowl and is upwardly inclined towardsthe rear of the bowl as advocated in ourcopending application, Ser. No. 483,23

Hater under pressure issuing from the nozzle will therefore be projected in an upwardly inclined direction towards the rear of the bowl. More particularly the direction of the fluid jet issuing from the nozzle will be such that the fluid under pressure will strike directly against the body outlet of the occupant of the seat in connection with which the cleansing operation is to be performed. r

In the arrangement described in said application, the flushing or water delivery arm is caused to travel in a substantially horizontal direction between its two extreme positions, the underside of the rim of the bowl being just about at the level that the nozzle should occupy when brought to its operative position, Due to this manner of operation, the arm remains constantly within the bowl and is exposed not only to theaction of .the flushing water issuing fromthe rim of the bowl, but also to contamination by residues which might remain in the bowl after improper flushing or otherwise. Sanitary considerations have therefore lead us to believe that it is preferable for the flushing or .water delivery arm to remain normallyina position where the water used to flush the bowl and residual matters cannot reach it or conr taminate it. I v

Accordingly, the primary object of our invention is to provide in a sanitary attachment of the character specified, a flushing or water delivery arm so arranged that when inoperative it rests above the bowl and away from the cavityof the bowl, while when brought to operative position its nozzlewill remain below the level of the bowl with its axis remainingon. a vertical longitudinal plane 7 passing through the center of the bowl as previously described. i

Another object is to provide in a device of the character specified, where a flushing or Water delivery arm is movable from an inoperative position above the bowl to an operative position within the bowl, means for effecting the movement of said arm, whereby said arm is subjected to both a translatory and a rotatory movement, this malring'it possible for said arm to remain flat above the bowl when in its inoperative position and to lay in a vertical or nearly vertical. plane when groulght to its operative position within the ow I A further object is to provide in a device of the class'specified where a flushing arm is caused to move from an inoperative position above the bowl to an operative position within the bowl, operating means of a novel and improved design, whereby said arm can be caused to acquire a translatory and a turning movement through a single movement of the operating member. A

A still further object is to provide in a device of thecharacter specified, where an opera-ting memberis caused by a single movement to impart to the flushing arm both a translatory and a rotatory movement, means whereby the same operating member is en- A abled by a continuation of its movement to also control the fluid flow through said flushing arm.

Other objects and advantages of the present'invention will more fully appear as the description proceeds and will be set forth and claimed in the appended claims.

Fig. 20 is a fragmentary front elevation illustrating a different type of valve operating plunger; and

Fig. 21 is a similar view illustrating a still different type of valve operating plunger.

Referring to said drawings, 20 designates atoilet bowl of usual construction comprising a base 21 and a rim 22 formed with a passage 23, through which water flows through a suitable source of supply in order to flush the bowl in the customary manner.

The bowl is provided with a seat 24 on top, hinged at 25 to the rear of the bowl. The lower surface of the seat 26 is usually provided with rubber spacing feet 27 resting upon the top. of rim 22 causing a clearance 28-to remain bet-ween the top of the bowl and the lower surface of the seat. The device illustrated, comprises a supporting frame 29 upon which all the operating parts are moun ed, said frame having a hook shaped arm 30 inwardly extending therefrom, said arm beingadapted to embrace the rimportion of the bowl and cooperating with two clamping screws 31, 32, in adjustably securing the device in position.

To this end, arm 30 is composed of a horizontal section 33 inwardly extending from the top of upright 34 of frame 29 and a clownwardlyi turnedend section 35 embracing the inner portion of rim 22. Arm 30 is preferably securediin position-by means of a screw or screws, such as 36 so as to make it easier to set the device in position and to remove it therefrom. Clamping screws 31, 32 are located one ateach side of upright 34 and can be caused to firmly grip the rim portion of the bowl so as to securely fasten the frame in position.

It will be observed that by adjusting the relative positions of said screws, the downwardly directedsection 35 of arm 30 can act as a fulcrum for. the frame, which can thus be placed in the proper position with respect to the bowl. Said frame essentially comprises an. inner cross member 37 and an outer cross member38 joined by two substantially horizontal hollow members 39, 40.

The inner cross member 3'? is provided witha passage leading from side opening 41 to the passage 42 of horizontal member 40. Said inner cross member is also provided with a side opening 43 leading to the passage 44 of horizontal member 39.

Said openings 41, 43 are threaded or otherwise machined to receive a hot and a cold water pipe respectively, such as shown at The outer-cross member 38 comprises a central hollow body 46 and two extensions 47, 48 laterally projecting therefrom in opposite directions.

Central body 46 is bored to form a vertical chamber 49, closed at the top except for a central opening through which may project the stem 50 upwardly extending from the valve controlling plunger 51. The open lower end of chamber 49 is threaded to receive a plug 52 which retains in position the housing 53 inserted :within said chamber. The upper surface of said housing is preferably cupped as shown at 54 while the bottom surface 55 of chamber 49 is cupped in the opposite direction so that a packing 56 may be compressed between said two cupped or concave surfaces when pressure is exerted by plug 52 against the lower surface 57 of housing 53.

Housing 53 is formed with a central chamber 58, which is open'at the lower end and closed at the top except for a central passage 59 for the stem 50 of a valve controlling plunger. Said valve controlling plunger comprises a body portion 60 which registers with and is vertically movable within chamber'58, and stem 50 which as stated projects through the top of housing 53 and the top of central body 46,

The housing 53 is provided with two diametrically opposite vertical slots such as 61 through which are slidably inserted cam acting members 62, 63 laterally projecting from body 60 of the valve controlling plunger in diametrically opposite directions.

A spring 64 is interposed between the plug I 52 and the bottom surface of the valve controlling plunger and tends to constantly maintain the valve controlling plunger in its upward position against theupper surface of chamber 58, as Fig. 10 clearly shows.

Extensions L7, 48 are each provided with a horizontal passage 65, 66 through which are inserted stem portions 67 68 of valves 69, 70. The slots 61 in housing 53 are accordingly enlarged as at 71 to permit the tip ends of said stems 67, 68 to project through the walls of housing 53. The head portions of said valves are housed within chambers 72, 7 3 extending from the outer ends of extensions 47, 48 to the seats of said valve and to passages 65, 66. Chambers 7 2, 73 communicate with passages a l, l2 respectively of horizontal members 39, 40, and are closed by plugs 74:, 75, springs 7 6, 77 being interposed between said plugs and said valves and constantly holding the valves against their seats.

By virtue of this construction, it will be seen that if the valve controlling plunger is depressed against the action of spring 6 the two cam acting members 62, 63 will gradually force out valves 69, 7 0 against the action of springs 7 6, 7 7 and cold and hot water will be admitted to chamber 49.

The middle portion of housing 53 is turned down as at 7 8, so as to form an annular passage with the inner surface of chamber 49, and in correspondence of said annular passage is provided another passage 79 extending through a lug 80 rearwardly projecting from central body portion 16. The water admitted to chamber 49 will therefore find its way through passage 79 to chamber 81 provided within lug 80. Said chamber 81 is open at the top and is threaded to receive the threaded lower end 82 of a hollow stud 83 forming a vertical pivotal support for the flushing or water delivery arm assembly.

Said assembly comprises the delivery arm 84 proper which is carried by a chuck 85 rotatably mounted on the enlarged outer end 86 of a horizontal tubular member 87, the rear end of which is screwed into and carried by a supporting member 88 as shown at 89, said supporting member 88 being rotatably mounted upon the enlarged upper end 90 of stud 83.

All the connections between these various parts are made so as to insure tightness while at the same time, permitting rotation of supporting member 88 about a vertical axis and rotation of chuck 85 and flushing arm 84 carried thereby, around the horizontal axis of said chuck and of tubular member 87. To this end, a threaded hollow nut 91 is inserted over stud 83 and is screwed into the lower end of supporting member 88 as shown at 92. A packing is provided between nut 91 and supporting member 88 by inserting the washer 93 against the shoulder formed by the neck portion of stud 83 and its enlarged portion 90 and then inserting a packing ring 94; between said washer and the inner surface of nut 91. In this manner, a pivotal connection is established between stud 83 and supporting member 88 which prevents said supporting member from coming 0E said stud and at the same time permits said supporting member to rotate upon said stud, packing ring 94: insuring the necessary tightness between these variousparts.

Stud 83 is provided with a central axial passage 95 which is closed at its upper end and which communicates by means of radial passages 96 with an annular passage 97 formed in the outer surface of the enlarged 1 portion 90 of the stud in correspondence of passage 98 of tubular member 87. Said passage 98 extends all the way from threaded end 89 of tubular member 87 to the outer end of 99 of enlarged portion 86 of said tubular member.

The arm holding chuck comprises a bushing member 100 which is rotatably mounted upon enlarged end 86 of tubular member 87, and which is formed with a tapering outer end '101 having a relatively thin edge 102, said tapering end being machined exactly to size at 103 to closely fit the attaching end of arm 34.

The outer surface of bushing 100 is threaded at both ends so as to be adapted to receive a threaded chuck collar 104 at its outer end and a threaded hollow nut 105 at its inner end. A washer 106 is inserted between the inner end surface of bushing 100 and the inner surface 107 of nut 105 and a packing ring 108 is inserted between said washer and said inner surface 107. This arrangement insures the tightness of the connection between the bushing and the nut and between the bushing and its support 86.

Chuck collar 10% is screwed onto the outer end of bushing 100 and has the outer end of its opening tapering as shown at 109, its tapering angle being slightly greater than the tapering angle of outer-end 101 of the bushing. By virtue of this arrangement, if the chuck collar is turned so that its inner tapering surface will tightly bear against the edge 102 of the outer end of the bushing, said edge will be forced inwardly and will tightly clamp the end of the arm 84 inserted within opening 103.

In this manner, the angular position of arm 84 can-be adjusted with respect to theaxis of tubular member 87 and when so adjusted said arm together with parts 100, 104, and 105 forming the chuck can rotate over its support '86 while tightness of the rotatable connection thus established; is insured by. packing ring 108- The. outer end of arm 84- is bent in an elongated i3 shape as shown at 110 and its angular position with respect to the axis of tubular member 87 is adjusted so that when said arm occupies its inoperative posit-ion shown in full lines in Figs. 1, 2, 3, 1, said 8 shaped outer end lies in a horizontal plane just above rim 22 at the rear of the bowl within clearance 23 between the upper surface of said rim and the lower surface of seat 2 1. Tubular extension 87 carries two rollers 111 and 112, roller 111 passing through horizontal slot 113 provided through the vertical wall 114 of an angle shaped arm supporting member 115. Said member 115 also has a horizontally extending flange 116 which has a slot 117 within which is inserted 'the'upward extension 118 of a cam acting dog 119 integral with bushing100. When arm 84 is in its inoperative position shown in Figs. 1 to 4, the flat upper surface 120 of dog 119 rests against the under surface of flange 116, as Fig. 8 clearly shows, so that in this position arm 84 is prevented from turning.

If said arm however, is moved angularly about its pivotal support 83 towards the center of the bowl, the tip of extension 118 of dog 119 will strike against the edge 121 of slot 117 and will cause the arm and the chuck from which it extends to turn about the axis of tubular member 87.

Roller 112 is engaged by a cam acting slot 122 provided in a vertically movable plunger 123, said slot having an upwardly inclined portion 124. and a vertical end portion 125. Plunger 123 is guided by and slidable between two uprights 126, 127 and is normally held in its upward position shown by springs such as 128, 129. At its upper end, said plunger is equipped with a push knob 130. lVhen downward pressure is exerted against said knob the inclined portion 12 1 of cam slot 122 will cause the flushing arm to move towards the center of the bowl until its proper position shown in dotted lines at 110 in Figs l and 2 is reached. At this point the flushing arm becomes engaged by the vertical portion 125 of slot 122 and will be retained thereby in the same position while the plunger continues to descend. At the beginning of the inward movement of the flushing arm to operative position, its 8 shaped end portion will retain its horizontal alignment until having cleared the rim of bowl, and extension 118 of dog 119 having come to rest against the edge 121 of slot 117 the arm will begin to rotate together with its chuck about theaxis of tubular member 87 as explained.

The lower end of vertically movable plunger 123, which is preferably fiat in shape as shown, is inserted within a slot 131 provided at the upper end of stem 50, and thus serves to maintain the proper alignment of valve controlling plunger 51 and housing 53. During the first period of the movement of descent of plunger 123, while the inward movement of the flushing arm takes place, the lower edge 132 of plunger 123 travels towards the lower end 133 of slot 131.

lVhen the vertical portion 125 of slot 122 begins to engage roller 112 of tubular member 87, lower edge 132 of plunger 123 meets lower edge 133 of slot 131, so that a continuation of the downward movement of plunger 123 will result in the valve controlling plunger 51 being forced downwardly against the action of spring 6 1. lVhen this takes place, cam acting members 62, 63 will force valves 69, 70 outwardly so that water will be admitted to the annular chamber forced by recess 78 and by the inner surface of chamber 49 and from there to passage 79 and to the flushing arm. To this end, the valve stems 67, 68 are formed with lon itudinal grooves such as 13 1, 135, in Figs. 18, 19 which will establish communication between chambers 72, 73 and said annular chamber.

Said longitudinal grooves 134, 135 preferably have curved outline at their inner end as shown at 136, in Fig. 10, so that the water is admitted to or out off gradually from the passages when the valves are opened or closed. This insures a condition whereby the pressure of the water will not interfere with the operation of the valves either way, preventing a sudden inflow, and especially obviating the possibility of the valve being held open'by the inrushing water after once having been forced open, an occurrence which might take place if the flow of water were only controlled by the conical seat of the valves.

It will be observed that while cam acting member 62 is shaped to first force valve 69 outwardly and then to permit said valve to once more gradually close, once the peak 136 has been passed, cam acting member 63 will first force valve 70 outwardly, then it will allow said valve to remain stationary, and then it will once more force said valve outwardly as the valve controlling plunger reaches the end of its downward stroke. By virtue of this arrangement the total flow of water controlled by the two valves will. be maintained about constant, since while the flow through passage begins to decrease the flow through passage 66 begins to increase.

Valve 69 controls the cold water supply while valve 7 0 controls the hot water supply and by virtue of the arrangement described, it is possible, when the movement of the valve controlling plunger starts, to deliver to the flushing arm water which is entirely cold. Then when the valve controlling plunger has reached about midway of its stroke, the water delivered would be a mixture of cold and hot water, and when the plunger has reached the end of its downward stroke, there will be no cold water delivered but only hot water. In this manner, it is possible for the user to regulate the exact temperature at which the water is delivered at the point of use. A parallel result may be obtained by means of the arrangement shown in Fig. 20 in which 67 is the stem of the valve controlling the cold water supply and 68 is the stem of the valve controlling the hot water supply. In this arrangementthe valve controlling plunger 51 is provided with two arms 137, 138 pivotally mounted at 139,140 respectively, said two pivots being vertically spaced from each other and pivot 140 being at a higher level than pivot 139. Arms 137, 138 have curved ends shaped to engage the rounded ends of valve stems 67 68' and therefore will form therewith a sort of toggle joint which results in valve stems 67 68" being forced outwardly when the valve controlling plunger 51' is forced downwardly.

However, arm 137 will reach its dead point before arm 138 so that arm 138 will continue to force valve stem 68' outwardly when arm 137 permits valve stem 67 to once more move inwardly after the dead point has been passed. An equivalent arrangement is shown in Fig. 21 where instead of using pivotally mounted arms we make use of two rollers 137, 138, rotatably mounted on vertical space shafts 139, 1 10. In this arrangement, the action of arms 137, 138 is duplicated the rollers acting as rolling cams while in the previous case arms 137, 138, act as elements of a toggle connection.

From the foregoing, it will be seen that we provide a simple, practical and reliable device in which a single movement ofan operating member causes the flushing arm to perform both a translatory and a rotary movement, and also causes water from suitable source of supply to reach the nozzle of said arm at the proper time,

Our invention may be carried into practice in ways different from that shown without departing from the inventive idea; the drawings will therefore be understood as being intended for illustrative purpose only, and not in a limiting sense. Accordingly, we reserve the right to carry our invention into practice in all those ways and manners which may enter, fairly, into the scope of the appended claims.
